Doomsday Bunker Upgrade

Just how powerful the system's functions can be, Chen Xin does not know, and the results he analyzed are only the product of the black hole above the neck of the Internet writer.

But this does not prevent Chen Xin from using the system, and knowing how to use it can make the system achieve his expected ideas.

"But before that, let's do business first!" Chen Xin took a deep breath, closed his laptop, cleaned up the remnants of breakfast, and came to the radio station.

The sudden temperature drop last night had a great impact on someone like him who had solid and reliable shelters, and it was hard to imagine what those shelters in the city would become.

Especially a few group friends in the urban area, Chen Xinke still owes them six oxygen generators! Before these 600 survival points were collected, Chen Xin didn't want them to go to the street like this.

"Call, this is the writer. The temperature suddenly dropped last night, are you all okay?" The radio was turned on. Although it was not the fixed communication time that everyone agreed upon, Chen Xin still called.

"This is an old vegetable farmer. Last night, there was a blizzard in the city, and the temperature dropped by 30 degrees. Now it's only -35 degrees. It's terrible!" Li Wensheng was the first to respond to Chen Xin, his voice was full of distress, and it was obvious that the cooling down last night had caused him a great loss.

Through Li Wensheng's words, Chen Xin learned what happened last night, and also had a clear understanding of the impact of the blizzard that suddenly fell last night.

Chen Xin's situation is not bad because of the blocking of the mountain. Li Wensheng's shelter was built directly under his villa. In terms of thermal insulation and thermal insulation performance, it is undoubtedly far worse.

From Li Wensheng's words, Chen Xin can tell that the temperature of his shelter has at least dropped below zero, otherwise the vegetables in his greenhouse will not be frosted.

Thinking of this, Chen Xin couldn't help feeling a little worried for them.

Although private shelters are built underground like official shelters, people with a bit of money can achieve the same thermal insulation measures as official shelters built by the state, but this will undoubtedly greatly increase the cost.

Just like Chen Xin's shelter, he made a polyurethane insulation layer in the wall, which also accounted for a large part of the cost of building the shelter in the first place.

But this is not something that everyone has enough funds to get, such as the "doctor"'s house. Chen Xin knew that he did not make polyurethane insulation because of financial problems, but used foam.

Li Wensheng is a little better than the "doctor". He uses ultra-fine glass wool, while Mo Qingyan uses the same polyurethane as Chen Xin.

Foam plastic and ultra-fine glass wool are both thermal insulation materials used in aircraft cockpits and cockpits. Although the performance of foam plastic is not bad, it is worse than the effect of ultra-fine glass wool, let alone Said compared to polyurethane.

As for the shelters of other groups of friends, although they are also equipped with thermal insulation materials, most of them are made of the same foam as the "doctor"'s home.

Although this relatively cheap material has average performance as a thermal insulation material, the price is very affordable, and it is indeed a good choice for those who do not have much money to build a private shelter.

Just in the face of this blizzard that cools down by 30 degrees overnight, there is a question mark about how much foam plastic can play.

Fortunately, with Li Wensheng's voice, the others also responded after hearing the call. After all, the blizzard brought about 30 degrees of temperature overnight, and everyone was seriously affected. At this time, contact others in time. , it is possible to get help.

Listening to everyone reporting their situation one by one, Chen Xin couldn't help feeling a little heavy.

Aside from him and Mo Qingyan, two of the ten shelters built by group friends in the urban area could not hold up, so they chose to send a distress message to the official shelter.

Chen Xin knew that the two group friends who gave up their shelters were converted from small garages. Although they were still well-equipped, well-prepared, and had a lot of supplies in stock, it was clear that their shelters faced this level of difficulty. The severe cold still lacks sufficient resistance.

If it's not really going to last, who will put a comfortable private shelter and squeeze the official shelter?

The abandonment of the two group friends made everyone feel a little heavy, and Chen Xin wanted to do something for them.

It's just that even though Chen Xin has a system that can help them, the two friends who chose to give up are no longer able to withstand the severe cold. They can only use the fuel reserves in the shelter to light a bonfire to keep warm, waiting for official rescue. Can't last too long.

Unless Chen Xin can build heating equipment in the shortest time or provide them with better thermal insulation measures, the only thing waiting for them is to freeze to death.

But the blizzard outside didn't stop. Even if Chen Xin wanted to save people in this weather, he didn't have the ability to save people. In this weather, it was impossible for Chen Xin to drive out against the blizzard.

However, Chen Xin still said in the communication channel: "Everyone, I can make a ground source heat pump device that uses ground temperature for heating, but making this equipment requires a compressor, an evaporator, a condenser and an expansion valve.

In simple terms, you can understand it as an air conditioner, and the materials needed to manufacture the equipment are all on the air conditioner. As long as you can bring me these parts, I can make the ground source heat pump unit for you. "

"Are you kidding about the ingredients? Can you really build a ground source heat pump?" Mo Qingyan questioned Chen Xin. She and Chen Xin were too familiar with each other, and she had never heard that Chen Xin had such talent.

And since Chen Xin has such ability, why didn't he say that he could manufacture ground source heat pumps before the disaster?

At that time, whether they were collecting materials or installing equipment, they had far more resources to use than now, and it was more convenient.

"I can make it, but it requires a lot of materials to make such a device." When Chen Xin heard Mo Qingyan's questioning, he naturally understood that his behavior was suspicious, but he still explained: "I have been looking at machinery these days. Manufacturing books, accumulated a little experience, it is no problem to make a device like this, as long as you can provide the materials."

There may be no problem with making the equipment, but it's clearly not the end of it when the equipment is made.

Although Mo Qingyan believed that Chen Xin could indeed manufacture a ground source heat pump device as heating equipment, she still asked Chen Xin, "But Ah Xin, you said that the ground source heat pump pipeline should be buried underground, right? Even if it is not used. A few hundred meters deep, tens of meters is still necessary? Now the temperature is minus 30 degrees, and the ground has already frozen hard, so what should we use to drill holes in the ground?"
